Аннотация
Morphological and immunohistochemical (IHC) analysis of bone marrow biopsies (BMB) is routinely performed during staging of patients with non-Hodgkin's lymphoma (NHL). Aiming to evaluate the possible diagnostic value of flow cytometry (FC) on bone marrow aspirates (BMA), as compared with BMB, we retrospectively reviewed BMA specimen of 354 NHL. In 305 cases (86.1 %), there was a concordance between the two investigations. A discordance was detected in 49 cases (14 %): in 33 of these (9.3 % of total population), FC analysis of BMA was positive, whereas BMB, supported by IHC, was negative; in 16 (4.5 % of total population), FC did not detected lymphoid infiltration, while BMB was positive. Although the clinical implications of such an observation remain unclear, we think our results may be useful in the context of current staging procedures, also opening a possible future perspective in the setting of minimal measurable disease in these patients.
